Notice the hole and there's a commotion (3)
I believe the answer is:
ado
'there's a commotion' is the definition.
(ado is a kind of commotion)
'notice the hole' is the wordplay.
'notice' becomes 'ad' (short for advert).
'the hole' becomes 'O'.
'ad'+'o'='ADO'
'and' is the link.
(Other definitions for ado that I've seen before include "Goings-on" , "Fuss or bustle" , "Hoo-ha" , "Busy activity, trouble" , "stir" .)
